Be it known that I, 'DAvID HINpAHt, a

citizen oat-the United States; residing'at cago, in the county 0 Illinois, have invented certain newend Doorstops; 0t which the track and-"may injnre thetdoors or V to provide means associated means so constructed as to .heireedil y':operswing ful Improvements in the following ise, sp

This invention'rela'tes to a new reilway'cegrs and more particularly to a device"adapted t-o limit -the proved door stop for i (look and State'of movement of laterally swinging doors upon dump cars. 1

Anumber of types constructed are provide swinging doors either of dump cars, as

now

d with laterally simply over the trucks e or throughout the, full" lengthof the car.

These doors 5 are positively latched or looked shut when the car is loaded. The" doors unl etched,

When in this latlerposition the link and pin positively prevent-the door from swinging outwardly beyond the side of the car, and thus prevent damage due to the swinging door if it shouldbe left unlatched in thatpositioir.

While, my device has type of'car, it is obviously not limited in its application to cars of that design, but maybe applied to swinging doors of any type; 1
